SSC MCQ Question Ans. Periodic Table
SSC MCQ Question Ans. Periodic Table. Periodic Table is a conceptual diagram of the properties of the elements expressed in the table. Total of 118 elements is detected up to the year 2012. It is not possible to remember all the properties of each element separately. In Periodic, Table elements are classified on the basis of their properties. From the periodic table, we can assume the chemical behavior of an element. Starting with the invention of the periodic table, its applications and significance are discussed in this chapter.
SSC MCQ Question Ans. Periodic Table
Periodic Table is the outstanding reflection of collections of different chemical concepts gathered over hundreds of years. From the beginning, scientists made attempts to give a combined shape of the concepts about elements and their properties gathered in a scattered way. This, later on, helps classify the elements on the basis of their properties, that is, lead to the introduction of the modern periodic table.
Molecular geometry, also known as the molecular structure, is the three-dimensional structure or arrangement of atoms in a molecule. Understanding the molecular structure of a compound can help determine the polarity, reactivity, phase of matter, color, magnetism, as well as the biological activity.
Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules, and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.
Chemistry is a branch of science that involves the study of the composition, structure, and properties of matter. Often known as the central science, it is a creative discipline chiefly concerned with atomic and molecular structure and its change, for instance through chemical reactions.
The days are long past when one person could hope to have detailed knowledge of all areas of chemistry. Those pursuing their interests into specific areas of chemistry communicate with others who share the same interests. Over time a group of chemists with specialized research interests becomes the founding members of an area of specialization.
The areas of specialization that emerged early in the history of chemistry, such as organic, inorganic, physical, analytical, and industrial chemistry, along with biochemistry, remain of greatest general interest. There has been, however, much growth in the areas of polymer, environmental, and medicinal chemistry during the 20th century. Moreover, new specialties continue to appear, as, for example, pesticide, forensic, and computational chemistry.
This course provides students with the opportunity to develop their knowledge, understanding, and skills in relation to properties and structures of matter and a variety of chemical reactions incorporating organic compounds and acid/base equilibrium reactions.
Chemistry is one of the diverse branches of physical science. It is known as the science of life. The practice of chemistry has been in a constant increase since the ancient time. The present-day chemical industries have been evolved from the early practices of the Alchemists. Chemistry as a discipline encompasses a wide range of areas. It has always been devoted to the welfare of human and its environment.
